" Specification of Letters l atent. Patented J l 2 9', 1919 ApplicationfiIed OetOber 25, 191s. serial No. 259,666.

To all whom it may concern:

Be it known that I, ANTHONY P. FERN, a citizen of the United States,residing at.Dun-' kirk, in the county of Chautauqua and State of NewYork,have invented certain new and useful Improvements in Music-LeafTurners, of which the followingis a specification.

This invention relates to music leaf turners, and the object thereof isto provide a simply constructed and efficient apparatus of thischaracter which may be used in connection with any piano or on any musicstand and in which the turning mechanism is actuated by keys operable atpoints remotefi Another object is to provide an apparatus of thischaracter having'simple and eflicient leaf turning members operatedautomatically on the releasing of a catch. i p

\Vith the foregoing and other objects in view, which will appear as thedescription proceeds, theinvention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein'disclosed may be made within thescope of what is claimedwithout departing from the spirit 'oftheinvention.

In the accompanying drawings D Figure 1 represents a front elevation ofa portion of a piano showingthis improved music lea-f turner applied.

Fig. 2 is a vertical section taken on the line 22 of Fig. 1,

Fig. 3 is a detail vertical section through the lower portion of theapparatus,

Fig. 4 is a vertical detailsection taken on Fig. 5 is a front elevationon small scale showing the turner constituting this invention-detached.

Fig. 6 is a detail sectional view; I

In the embodiment illustrated, the turner constituting this inventioncomprises a supporting or'backboard 1 having a laterally and forwardlyprojecting flange 2 at its lower edge on the bottom of which is mounteda strip 3 covered by an anti-friction material, 4, and which is designedto rest on the music shelf S of a piano. as is shown clearly in Fig. 2.A strip 5 of felt or other suitable anti-scratching material is securedto the rear face of the board 1 at its'upper edge (seeFig.2).

Depend'ng from flange 2 are a plurality of hangers 6 having rearwardlyand laterally extending apertured lugs 7 for attachment to the lowerface of the flange 2 and forwardly extending arms 8 at their lower'ends. Four of these hangers 6 are here shown, although obviously anydesired number may be used, and they have nuts 8 and screws 8 to preventtilting of the board.

A rod 10 is supported midway the length offiange 2 and is mounted in anapertured ear 11 projecting laterally and forwardly from the upper'edgeof board 1 as is shown I clearly in Fig. 1. This rod 10 has a knob 12 atits upper end and is provided at points below said knob'withcollars 13which are designed to support hinge members herein after to bedescribed.

Leaf supporting frames 11 are hingedly connected with the rod 10 anydesired number'of which may be employed, two being here shown. Each ofthese frames comprises an upright outer bar 15 connected with an innerbar 18" by cross bars 16 and 17 which form the top and bottom members.of the frame. The top'and'bottom members 16 and 17 and the inner member18 of each frame has'an inturned laterally spaced flange 19 to formreceiving pockets for the sheets or leavesL to be supported by saidframes.

' Th'e'inner bars of the framemembers have hin e'd knuckles 20 and 21which are pivotafiyfl'engaged with the rod 10 which form the pintleforconnecting the frames. The upper hinge knuckles 20 are designed torest "on and be supported by the collars 13 carried by rod 10. Arrangedabove the lower 'lmuckles 21 are coiled springs 22'and'24, the

"spring 22 being'connected at one'end with the rod lOand. having alaterally extending 'finger 23 which engages therearface of therearframe member 18 as'is shown clearly in Fig. 1, while the spring 24has a similar Ifinger 25 which engages the rear face of member 18 of theother frame, so that these below these catches 26 to force them upwardlyinto engagement with the lower frame members 17 as is shown clearly inFig.

40f the drawings. Wires or other suitable connecting elements 29 areattached at one end to the noses of the catches 26 and at Fig. 3;

their other ends are secured to two of which are here shown, one foreachcatch member. These rods 30 are mounted for vertical movement inbearings 31 carriedb'y' the brackets or hangers 6.

Rods 32=areniounted in :the hangers 6 between the laterallyextendingarms .8 thereof and said bearings 31 as is shown clearly in u Coiledsprings 33' are mounted on these'rods and between their upper ends andthe bearings 31 are disposedthe ends of cross rodsv34c, two of which arehere shown, said springs exerting their tension .to force said rods 34upwardly.

Connectors in th former metal' pl'ates 35 connect the rods 30 and 34L sothat when one of these rods is moved the other will be movedsimultaneously therewith fora-purposepresently to be described.

T-shaped metal castings 36 are carried by the rods 34: said rodsextending through the heads of these castings and having recesses In theuse-of this music leaf turner when' applied. to a piano 'as s-hown inFigs-.1 and 2, the board. 1 is supported on theishelf S l with the feet4:1.carriedlby the T-shaped I sheet. or music alltha-tis necessary istode-.

It will be obvious that when these actuatingv feet 4P1or 41 are released, that the springs 33 will automatically return therods 34 and 30 to normal position and the springs 28will force thecatches 26 upward into position for engagement with the.

frames 14 whenthe l tter are's'wung laterany toward the right toresetting them.

p The foregoing descrip ion and the drawings have reference to what maybe considered the preferr cl'or approved form. of my invention. It isltobe understood that I may 'nrake such, changes in construction andarrangement and combination of parts, ma-

terials, dimensions etc, as may prove expedient and fa l'l iwithinclaimed invention. V v
